INVENTOR LOUIS N.D.WILLIRMS 0v ms RTTORNEY 2, hut showing LoUIsN. n. WILLIAMS, or OGONTZ,

To all whom it may concern g Y Be it known that I, Louis NLDLW L- 'mAMs,a citizen of the .United S tates; residing in olgontz, Pennsylvania, hairs invented certain Improvements in Stitch Transfer ring and Uniting Devices, of which thei'ollowingis a specification.

M invention relates-t0 a rnethodofunitpoints. (hereinafter, for convenience, poi-rite) with the stitches to be united, then adjusting said. sets of points, -,With the to one stitches upon tnen1,.into close relation another, and then uniting, by means of a separately reduced chain of] stitches, sue" cessive stitc 1630B successive pairs of stitches of the knitted Web, stlll upon the original transfer points and without transferring the stitches of one set of points, onto the other set of. points.

My invention further relates to the dis engagement of thepoints, and stitches aiiter the webs have been united.

These objects ina'fter set forth; reference being had to the accompanying drawing; in which Figure]. is a sectional view of sufiicient of a circular knitting machine to illustrate the application thereto of a device in accordance with myinvention for engaging the stitches of the knitted Web carried said machine said device hein in position to receive said stitchesyifiig. 2 1s a sectional view on a lar er scale.

of said device with the stitch engaging I of the uniting of the successive stitches of the knittedwebs; views illustrating successive steps in the operation of disengaging said stitch engag ng put its from the 1. butillustrating still another form of st tch engaging device; Fig. 11 is aviewfof said device with thestitch-engaging points adjusted to position for the uniting of the successive stitches otthe knitted webs, and

Fig.1.! is an enlarged diagram, illustrating the stitches whereby said successive stitches of the knitted Webs are unites In the drawing I have only shown a single pair of diametrically opposite Wales, and the points which engage them, as the sh-owingof the other Wales and points would only cause confusion.

The stitch engaging ..(levi(:e may, in the case of a circular web, consist of two semi circularsegments 1 and 32, each provided with a segmental series of stitch. engaging points 1 or )flwhich, when the segments 1 and 2 are in the position shown in Fig. 1,. will engage the stitches upon the needles of knitting machine or the stitches of a,- previous course. Each point 1? of the segment 1 corresponds Witha pointfl of the segment 2 andthe stems it and 2 of the stitch receiving points shown injFigsjl, 2 and 3 project beyond the segments land 2 and said projecting portions of the stems are so bent that when. the segments are folded, as shown in Fig. the corr pond: ing points 1 and '12 will ah: against each other hack to back and "wiliprevent the segmental and 2 from being hroug zht'rlosc t together. \Vhcn the pointsare in this positof the Webs are close enough to be united in pairs by a chain of stitches y, as shown in Fig. After this one of the, segments is shogged slightly inrespcct to the other so as to alternate the points i and ,2, asshown in Fig. 5. and thus permit thescgmcnts l and 2 to approach each other hack to hack, asfshown in. Fig. 3, and thereby disengage stitches a. .1, after which the entire point structure can hc readily removed from between the two webs. i 1

When the chain elf-stitches 3;. which consimilar to nects the stitches m, w, of the webs is relatively slack, a stitch engaging device such as shown in Figs. 6 to 9 can be employed, the segments 1 and 2 of such device having stitch engaging points 1 and .2- with straight shanks which permit of the folding of the segments back to back, as shown in Fig. 7 without withdrawing the points 1 and 2 from the stitches carried thereby, but the uniting chain of stitches y will permit the entire point carrying structure to be moved laterally so as to disengage one set of points, say the points 1, from the stitches m of its web, as shown in Fig. 8, after which the segment 1 and its points 1 can be removed from between the webs, as shown in Fig. 9, in order to permit sidewise movement of the segment 2 and its points to an extent sufficient to free the latter from engagement with the stitches w of its web and subsequent removal from between the webs.

It may be advisable in some cases to provide the segments shown in Figs. 1, 2 and 3 with an elastic band 5 seated in grooves in the segments and tending-to draw saidsegmcnts toward each other either when adjusted edge to edge, as shown in Fig. 1, or when adjusted back to back, as shown in Figs. 2 and 3, but this is not essential, nor is it essential that the point carriers shall be in the form of segments, sinceywhen employed in connection with straight knitting machines instead of circular knitting machines, said point carriers may consist of straight flat bars.

The stitches of the connecting chain l shown in Figs. 7, S and 9 may be slack enough to vrmit disengagement of the points 1 an 2 from the stitches a: without affecting either the secure retention of said stitches or impairing the appearance of the connecting seam.

In: that embodiment of my invention shown in -Figs. 10, 11 and 12, the points 1 and 2, after receiving the stitches from the needles of the knitting machine, are brought together and alternated, as shown in Figs. 11 and-12, so that the points may overlap,

and thus bring the terminal stitches a of the twowebs close enough to be united by a chain of stitches y which engages with successive individual stitches :r of each web, as shown in Fig. 12, instead of uniting the stitches in pairs, as shown in Fig. 4.

I claim 1. The mode herein described of uniting the terminal stitches of knitted webs, said mode consisting in engaging one set of said stitches with one set of stitch -engaging points and the other set of stitches with another set of such points, then, without removing the stitches from their engaging points, bringing said stitches into proximity to one another, then uniting them by means of an independently produced chain of stitches, and then disengaging each set of'points from the stitches engaged thereby. 2. The mode herein described of uniting the terminal stitches of knitted webs, said mode consisting in engaging one set of said stitches with one set of stitch-engaging points and the other set of said stitches with another set of such points, then bringing the two sets of stitches into proximity to one an-. other, then, without removing the stitches from their engaging points, uniting said webs by an independently producedghain of stitches, each stitch of said chain engaging a pair of stitches, comprising a stitc each web, and then disengaging each t of points from the stitches enga ed thereby.

3. The mode herein described of unitin the terminal stitches of knitted webs, sai

mode consisting in engaging one set of said stitches with one set of stitch engaging points and the other set of stitches with another set of such points, then bringing the two sets'of stitches into proximity to one another, then, without removing the stitches from their engaging points, uniting said webs by an independently produced chain of stitches, each stitch of. said chain engag ing a pair of stitches comprising a stitch of each web, then shogging the stitches of one web in respect to those of the other web so as to cause them to alternate, and then dis; engaging each set of points from the stitches engaged thereby.

In apparatus for effecting the uniting of the terminal stitches of knitted webs, the within described means for engaging said terminal stitches and adjusting them into position to be united. said means comprising a pair of bars adjustable edge to edge or back to back, and each carrying a set of stitch engaging points projecting therefrom in a plane at a right angle or thereabout to the plane of the bar.
